Hey, im new to watercooling but i understand just about everything that goes into it. but the one thing im shakey on is the fittings concept. i will be bending my tubing with a heat gun so, which saves. money as it rids the need of extra fittings, but i still do not know how many to buy and what kind. i should only need 90 degree ones but i need that confirmed. i will be doing this in the dark base 900 with a 420mm rad and a 240mm rad. 420 on top and 240 in the front. and also, if you know, i was wonfering if that case had a radiator mount built in. i would expect it but im still asking. ill be using a d5 thermaltake pump reservoir combo. thanks for any help
